Burger King has long been part of the American landscape, so it comes as something of a surprise to learn that the fast food monolith is only about to celebrate its fifth birthday in Japan. To celebrate over the next five days, they are allowing anyone who buys a black burger* combo meal a 30-minute opportunity to chow down as many burgers, fries and sodas as they can handle. Somebody call Kobayashi.

*The black burger, by the way, has black buns and black ketchup made from squid ink.
